Apple reportedly set a shipment target of 10 million iPad Minis for the current quarter. But in light of the production stall at AU Optronics, that number may reach only 6 million.

Production of the new-model iMacs is also running into delays. Responsible for the new iMac's panels, LG Display had to create a new process to mass produce the component. That process so far is yielding a limited number of parts, which in turn is stalling shipments, according to DigiTimes' sources.

The new 21.5-inch iMac will be available for consumers this Friday, while the 27-inch model won't start to ship until December.

Shipments of both products should rise early next year. That's when suppliers will begin to see higher revenue as they make more components for the new devices. At the same time, they should be able to bump up their production, helping Apple reach its shipment targets during next year's first quarter.
